Your posture is key in preventing or managing back
pain while doing your daily activities.
What is Neutral Posture?
Good posture means balanced curves. Balanced curves are when
the two curves, the one in our neck and lower back, curve in while
the other two curves, the one in our mid back and tailbone, curve
out. (See figure 6)

** Please note that this is a general representation of
the spine and is not meant to show its exact structure
Neutral posture is achieved when, looking from the side, your
ear, shoulder and hip are stacked one on top of the other, or
a line drawn through these 3 points would be straight. The four
curves are what allow us to stand upright as shown in figure
7.

Another way to access your posture and ensure the curves in
the spine are not excessive is to examine the position of your
pelvis in a standing position. If you think of your pelvis like
a bucket of water, a neutral position would be one in which the
water is held completely in the bucket. The pelvis can tip forward
which would allow water to pour out the front, or backward, with
water pouring out the back. Try to maintain a neutral pelvic
position, or keep the water in the bucket, throughout completion
of daily activities and while standing or sitting. (See figure
8)

Keep this neutral posture throughout the day, when you sit,
stand, lie down or move, think of keeping these curves in your
spine and keeping your pelvis or "bucket of water" level.
Why is Neutral Posture important?
Different positions apply different amounts of stress
on the spine; this is illustrated in figure 9. As
you can see, lying down places the least amount of stress on the spine.
Notice the different amounts of stress on the spine between standing
or sitting with neutral posture and standing or sitting slightly bent
forward. As you can see sitting slightly bent forward with weight
in the hands places the greatest amount of stress on the spine.
